Definitions

  • the present invention relates to a security and arming device for priming underwater charges, in particular military charges, and more particularly such a device of the type in which a pressure-sensitive detection member is movable between a first position that 'it adopts when the device is substantially at atmospheric pressure and a second position which it adopts when the device has reached a pressure from which the priming can be carried out.
  • French patent No. 2330512 also describes a device of this type applied to a pyrotechnic shear intended to cut submerged orins. These known devices have a number of drawbacks.
  • the arming that is to say the passage from the SECURITY position to the ARMED position.
  • the arming is indeed often caused by the depression of a hydrostatic piston sensitive to the external pressure, and consequently to the depth.
  • This hydrostatic piston plays the role of both an arming detector and an arming engine, and even possibly that of a pyrotechnic chain switch. It follows that the pyrotechnic chain switch leaves the SECURE-RTE position at the first request to progressively go to the ARMED position. During the passage from one position to another, one cannot know with certainty if the pyrotechnic chain switch still plays its role, so that safety is no longer guaranteed from the start of the movement.
  • the screen can move to a third sterilization position forming a pyrotechnic chain screen.
  • the release of this sterilization position is not caused solely by outside intervention, despite any subsequent movement of the detection member. Indeed, after a return to atmospheric pressure, the movement of the screen is not irreversible since, if the piston is again subjected to immersion, the switch member resumes movement towards its ARMED position.
  • We therefore see the major drawback of this embodiment which does not allow, in the event of an accidental rise of the system after its activation, a final and irreversible sterilization, except external intervention.
  • This system may be required to operate under conditions other than those provided, therefore dangerous.
  • the present invention aims to overcome these drawbacks.
  • a security and arming device for the initiation of underwater charges, in particular military, of the type in which a detection member, sensitive to pressure, is movable between a first position that '' it adopts when the device is substantially at atmospheric pressure and a second position which it adopts when the device has reached a pressure from which the priming can be carried out
  • device comprising a pyrotechnic chain switch member which, in a first safety position, where it is locked by the detection member when the latter is not in a second position, forms a screen across the pyrotechnic chain, and, in a second arming position that it adopts when the detection member reaches its second position, releases the pyrotechnic chain
  • the pyrotechnic chain switch member is arranged to move from its second position to a third sterilization position when the detection member moves back from its second position to its first position, the pyrotechnic chain switch member again forming, in its third position, a screen across the pyrotechnic chain and unable
  • the device does not remain armed, contrary to what was the case until now. On the contrary, it is neutralized in the STERILIZATION position, from which it can only be brought back to the SAFETY position or to the ARMED position after voluntary intervention.
  • the device comprises a timepiece mechanism capable of being triggered when the pyrotechnic chain switch member moves from its first to its second position and the pyrotechnic chain switch member is designed to be move from its second position to a fourth sterilization position after a certain period of time counted down by the clock mechanism, the pyrotechnic chain switch member again forming, in its fourth position, a screen across the pyrotechnic chain and cannot be released from this fourth position without external intervention despite any subsequent movement of the detection member.
  • the fourth position of the pyrotechnic chain switch member is merged with its third position.
  • the device comprises means for making the position of the pyrotechnic chain switch member visible from the outside.
  • the pyrotechnic chain interrupting member may, for example, comprise a rotor disposed between a primer and the rest of the pyrotechnic chain, this rotor having a hole placed in front of the primer in the second position of the rotor.
  • This hole can be left empty or contain an explosive transmission relay. Priming of the charge is possible when the hole is placed between the primer and the rest of the pyrotechnic chain, therefore in the second position of the rotor, but is however not possible when the rotor shields in its others positions.
  • the detection member advantageously comprises a hydrostatic piston, movable axially as a function of the external pressure, this piston having a section of reduced diameter, and a ball prevents the rotation of the rotor by remaining locked in a notch of this rotor by a generator of the piston when the latter is not in its second position, said ball allowing the rotation of the rotor when the reduced diameter section of the piston is opposite the ball when the piston is in its second position .
  • the reduced diameter section of the piston is disposed on this piston at a height such that, when the piston is pressed under the effect of pressure, it reaches the level of the ball when the device has reached the cocking depth . At this instant, the ball consequently unlocks the rotor which passes from its SAFETY position to its ARMED position.
  • the device may, moreover, comprise means for angular locking of the rotor in its second position, these locking means comprising a stop integral with rotation of the rotor and movable axially and means cooperating with this stop, the detection member being arranged to bring the stopper to an axial position in which it is likely to come into contact with the cooperating means when it detects a pressure greater than a predetermined value and to axially move the stopper from the cooperating means when the pressure again becomes lower than this predetermined value .
  • the device After arming the device, it remains in the ARMED position as long as the pressure is greater than the arming value. If the pressure becomes lower again, that is to say in the event of a rise, the device is released and can therefore leave the ARMED position.
  • a clockwork mechanism provided with an output shaft on which is mounted a first cam capable of cooperating with a stop integral in rotation with the rotor, this first cam being arranged to lock the rotor in its second position by being in contact with the stop for a predetermined time after the triggering of the clock mechanism and to release the rotor by disappearing from the path of the stop after this predetermined time.
  • a second cam can, moreover, be mounted on the output shaft of the timepiece mechanism, this cam being capable of cooperating with a stop controlled by the rotation of the rotor to prevent movement of the timepiece mechanism when the rotor is in its first position and to allow this movement when the rotor leaves this first position.
  • the clockwork mechanism is therefore triggered at the instant when the device changes from its SAFETY position to its ARMED position and counts down from this moment the time after which the load must be considered as not having worked.
  • the device advantageously comprises elastic means for bringing the rotor into a third angular position when, while it is in its second position, the rotor stop is released.
  • the rotor then preferably comprises a lock capable of engaging under the effect of an elastic means in a hole formed in a fixed member of the device when the rotor is in its third position.
  • the device according to the invention may also comprise a window through which are visible areas of the rotor identified differently, for example by colors, depending on the position of the rotor.
  • This window can, for example, be mounted outside the hole mentioned above, the identification zone of the third position of the rotor being provided by the end of the lock.
  • the device according to the invention may also comprise, in addition, electrical safety devices comprising at least one microswitch making the circuits active in the second position of the pytotechnical chain interrupting member and inactive in its other positions.
  • the microswitches can be, for example, arranged so that their actuating members cooperate with flats formed on a cylindrical part of the rotor to open or close the microswitches according to the angular position of the rotor.
  • the device generally comprises a housing 1 inside which are mounted a support member 2 and a cylinder 3.
  • the support member 2 rotatably supports a rotor 4, the axis of rotation is perpendicular to the axis of cylinder 3 and in cylinder 3 is slidably mounted a hydrostatic piston 5.
  • the piston 5 has its head 6 subjected to external pressure through an orifice 7 in the housing.
  • a membrane 8 held by the piston head seals between the outside and the inside of the device, while allowing movement. longitudinal of the piston.
  • a pin 9 the function of which will be described below, is accessible from the outside and, in the position where it is shown in FIG. 3, it prevents movement of the piston 5.
  • a helical calibration spring 10 disposed at the bottom of the cylinder 3 tends to cause the piston 5 to come out of the cylinder until a flange 11 of the piston abuts on an annular projection 12 provided on the interior surface of the cylinder 3.
  • the body of the piston 5 also comprises a section 13 of reduced diameter at its upper part and another part 14 of smaller diameter towards its lower part.
  • the rotor 4 is essentially formed by a flywheel 15 and a shaft 16.
  • a hole 18 is drilled in the flywheel 15 parallel to the axis of the rotor 4 and in this hole 18 is placed an explosive transmission relay 19.
  • Another hole 20 is formed at the periphery of the flywheel 15 perpendicular to the axis of the rotor 4.
  • a latch 21 is placed in the hole 20, this latch being hollow in order to receive a helical spring 22 which also bears on the bottom of the hole 20 to tend to make the latch 21 come out of the hole 20.
  • the latch 21 is however held in the hole 20 by the surface of the support member 2.
  • the member 2 however has a hole 23 in which the lock 21, as will be described below.
  • the rotor 4 has, moreover, an axial bore 24.
  • a rod 25 whose outer end is rounded in the shape of a hemisphere and whose inner end is pushed back by a helical spring 26 bearing on the bottom of hole 24.
  • a finger 27 projects from the rod 25 through the shaft 16 and preferably carries at its end a ball bearing 28 for reasons which will be explained below.
  • the shaft 16 also carries a screw 29, the head of which projects so that it can serve as a stop.
  • the shaft 16 also includes flats 30, shown in FIG. 5, capable of cooperating with the actuating members 31 of microswitches 32 mounted on the device housing.
  • the microswitches 32 provide various electrical safety features by short-circuiting the ignition capacitors and also allow an electronic firing timer to be triggered. However, the electronic part of the device, which is not part of the invention, will not be described in more detail.
  • the flywheel 15 of the rotor 4 finally has on its periphery, on the one hand, a circular notch 33 and, on the other hand, a groove 34 on a quarter of its periphery.
  • the cylinder 3 has, for its part, at the notch 33 and the groove 34, a hole 35, and a ball 36 can find a place both in the hole 35 and in the notch 33 or in the hole 35 and the groove 34 while being held by a generator of the piston 5.
  • the device also includes a clock mechanism 37 of any known type, the output shaft of which supports a first cam 38 and a second cam 39.

  • section 13 of reduced diameter of the piston 5 comes opposite the ball 36 which is no longer held in the notch 33 and therefore frees the rotor 4 in rotation.
